google keeps its street view reasonably up-to-date by refreshing it periodically, sending around new trucks with new and different cameras. this means that the street view glitchesi foundback in 2007 have long since disappeared.

but new trucks means new opportunities for glitches, as i discovered while digitally wandering the streets of indianapolis.

these glitches seem to involve a stitching error between the cameras at eye level and those pointed at the ground. if something happens to be physically close enough to the camera at near-ground level, it can end up pretty distorted:

a similar effect can be seen higher up—between the eye-level cameras and the ones pointed toward the sky—though it's less likely there'll be anything up there:

this last one's a real chance moment—a leaf fell on the camera:

update: click through the images to go to flickr... i've added street view links for most of them so you can see the glitches in their "natural" environment.

now is the moment you've been waiting for! the new stAllio! album a huge smash—the long-awaited full-length follow-up to mash smarter not harder—is now available for free download!

a huge smash is 11 tracks of glitchy post-mashup madness. it picks up directly where mash smarter left off, as i smash pop music into increasingly smaller pieces and then weld them back together in new and innovative ways.

this is a completely free download—it's not on itunes and there's no "pay what you want" feature. all i ask is that if you enjoy the album, please share it with your friends. post it on your facebooks, your twitters and reddits, or whatever it is kids do these days. i'm giving this to you for free, and all i'm asking is that you copy and paste the link a few times. that's a price you can't beat! ¶

i got a new computer in the past few months and was looking for an excuse to confirm whether the wordpad effect still works in windows 7 (it does, if slowly). so i figured i'd do a quick experiment to test a hypothesis discussed in the comments of part 1 of my databending primer—that the amount of warping caused by the wordpad effect is dependent on the relative brightness (or darkness) of the source image.

for my source image, i used variations of the same image: text on a solid background. i tried both white text on black background and vice versa, with the text at 25%, 50%, 75%, and 100% opacity. the black text on a white background showed no warping at all, regardless of opacity. this was consistent with similar experiments i've tried in the past, but still a bit puzzling.

the images with white text on a black background did warp, and hinted at a pattern. [all originals were saved in photoshop raw format, non-interleaved. all images are hosted on flickr; click to go there.]

100% opacity:

75% opacity:

50% opacity:

25% opacity:

pure white (100%) on black warped, but just a little. reducing the text whiteness to 75% produced considerably more warping, and reducing to 25% produced more still. this would suggest a pattern of the text warping more the darker it gets, but that wouldn't explain the result for 50% opacity, which is less warped than 75% or 25%.

since the black-on-white experiment was a bust, i figured i'd try a couple more, this time with solid black text on a gray background.

75% white:

50% white:

25% white:

the results are roughly analogous to those from the white-on-black images: 75% white warps more than 50%, whereas 25% warps most of all.

clearly, it would seem that the source image brightness has an impact on warping, but it's not as simple as darkening an image to make it warp more. ¶
